Question

Quizplus · Accepted Answer

The key detail in this question is that Viper needs to stay warm. This suggests that Viper is likely an ectotherm, which relies on external sources of heat to regulate its body temperature. Of the two options given for ectotherms - shivering or basking under a heat lamp - it makes more sense for Viper to bask under a heat lamp, which is a common behavior for reptilian ectotherms. Therefore, the correct answer is choice B: ectotherm; basks under a heat lamp.
